Chris Dodd, Managing Director of Purity Laboratories, discusses how to maintain the new, white smile after professional whitening treatments.

New research by the British Dental Health Foundation (1) found that one in five people now spend more money per month on oral care products, compared with hair products, skincare, fragrances and cosmetics. And, having seen a huge increase in the demand for professional whitening treatments over the past decade, it’s clear that the quest for a “Hollywood smile” is unlikely to end anytime soon! The ability to offer a professional tooth whitening service in your practice is an extremely attractive and lucrative treatment offering which will keep you at the cutting edge of cosmetic dentistry. In just one surgery visit, you can give your patients a brighter shade through treatments with bleaching trays, strips or laser treatment.

However, whilst we spend our time educating and encouraging patients to stop smoking after whitening treatments, reduce the intake of coffee and sugary snacks, the truth is that once the patient leaves the practice the maintenance of their new, white smile becomes their own responsibility.

The lows…

Patients are keen to minimise the effect of “bounce back”; a process whereby the teeth rehydrate and slightly darken a day or two after treatment. Enamel is naturally subject to abrasion but even more so after in-surgery treatment, because Hydrogen Peroxide and Carbamide Peroxide reduce the hardness of the enamel. Therefore, it is even more important that patients avoid highly abrasive whitening toothpastes as they can damage their teeth and gums, removing the lustre of the teeth and dulling a beautiful smile. By recommending a low-abrasion whitening toothpaste, you can ensure your patients protect and restore the enamel calcification lost as a result of the bleaching process, helping maintain their white smile for longer.

The abrasiveness of toothpaste is measured according to the RDA (relative dentin abrasivity) value, and any value over 100 is considered to be “abrasive”, something which is unfortunately often not included in marketing or promotional information supplied with toothpaste products, thus masking a common problem. Interesting, a USA-based independent testing laboratory (July 2012) tested the abrasion levels of 15 toothpastes. The results confirmed that Beverly Hills Formula’s whitening toothpaste is less abrasive than other leading brands of both whitening and regular toothpastes. In fact, Beverly Hills Formula Perfect White scored as low as 95 on the

Abrasivity Index Table, whilst some leading competitors displayed levels as high as 138.

And the highs…

To support these abrasion results, an invitro laboratory study found that Beverly Hills Formula whitening toothpastes remove stains in just one minute. Beverly Hills Formula Perfect White (coded as “PLMO/1×1158 Stain Removal” in the study) toothpaste proved effective at removing stains with almost 91% of stains removed over a five-minute period. Meanwhile, other leading brands of whitening toothpaste and tooth polishes scored as low as 41%, a remarkably low percentage, considering water alone removes 48% of staining (2). Click here for more information on how the study was conducted

These results signal a breakthrough in oral care and aesthetics, as this new generation of whitening toothpaste offers a tooth-friendly solution post in-surgery treatment, helping patients restore their teeth to a natural white colour for longer.

Whitening – no longer a sensitive issue

After in-surgery whitening treatments patients can experience sensitivity, this can be anything from a mild twinge to having severe discomfort for several hours, or even days. For these patients, why not recommend the use of a toothpaste that contains Potassium Citrate. This desensitising agent relieves tooth sensitivity by effectively blocking the transmission of pain sensations to reach the tooth’s nerves.

Those who require extra sensitivity relief alongside an extra whitening boost will appreciate the benefits of toothpaste like Perfect White Sensitive. Combining the advanced Hydrated Silica for high-performance whitening with Potassium Citrate for rapid sensitivity, patients can start to enjoy acidic foods and drinks once again whilst leaving teeth looking and feeling brighter. Regular use will also help to prevent tartar build-up and relieve tooth sensitivity, effectively protecting and allowing you to get that Beverly Hills smile without expensive whitening treatments
